180 KANSAS ACADEMY OF SCIENCE. 



Twenty-three of the thirty birds were taken in Kansas. No birds 

 were taken in April, June, July, August, or September, and but one 

 in May. 



Eleven of the thirty birds had eaten common Cottontail rabbit. 



Seven had eaten jack-rabbit. 



Nine had eaten prairie-dogs. Five of these had eaten more or less 

 of two different animals, as was shown by the food mass containing 

 more than two fore or hind feet, two tails, or two pairs of ears. 



One which was sent from Riley county in May, 1883, had in its 

 crop a mass of partly digested stuff that contained feet, some bones 

 and hair that seemed to belong to a young coyote wolf. 



One taken in October, 1889, in the northern part of the state of 

 Washington, had been feeding upon a woodchuck, presumably Arc- 

 tojiiys pruinosus, as this species lives in that locality. 



One specimen, taken near Lawrence, October 7, 1891, had eaten a 

 Franklin's gopher-squirrel {Spermophilus franklini). This speci- 

 men also had some hair and bones of a rabbit in its food contents. 



One bird, taken March 11, 1894, had the feet, some bones, feathers 

 and meat of a Short-eared owl {^Aaio accipitrinus) in its croi?. This 

 bird had also some rabbit bones and hair in its food mass. 



A specimen taken in Wabaunsee county, Kansas, November, 1885, 

 had eaten part of an opossum. Another, taken in Franklin county, 

 Kansas, January 25, 1902, had eaten a fox-squirrel. 



The last bird studied was taken November 17, 1904. It had parts 

 of a Cottontail rabbit and the foot and leg of a Red- tail hawk in its 

 crop. 



As a rule but one kind of food was found in the crop of each bird. 

 When more than one kind was present, it was usually some hard, un- 

 digestible material, as ears or feet, which had been left over from a 

 former meal. 



Twenty-three of the birds had fed upon rabbits or prairie-dogs, the 

 animals most common in the localities where the birds were taken. 



One hawk and one owl constitute the only traces of bird food found 

 in the stomachs of the thirty eagles examined. 



However, but one bird was taken during the months of April, May, 

 June, July, August, and September, the season of the year when birds 

 would perhaps be more likely to be taken for food.
